25 Claims. (Cl. 12-10.2)

This invention relates to machines for use in the manufacture of shoes and is herein illustrated in its application to a machine for pulling uppers over lasts. An immediate object in view is to provide certain improvements in pulling-over machines of a well-known type the main characteristic features of which are disclosed in United States Letters Patent No. 1,029,387, granted on June 11, 1912, on an application of R. F. McFeely. The invention is accordingly herein shown as applied to such a machine, but it is to be understood that in some of its novel and useful aspects it is not limited to machines of that type or to pulling-over machines.

A pulling-over machine of the above-mentionedl type is provided with a toe gripper for pulling the upper at the end of the toe and with side grippers for pulling it respectively at the opposite sides of the forepart. Associated with the several grippers are wipers which, after the pulling of the upper, wipe its margin inwardly over the insole and tackers which are thereafter operated to drive tacks for fastening the upper in pulled-over position. A single tack is thus driven at the end of the toe and usually tWo tacks are-driven at each side of the forepart, one tack at each side being preferably located substantially at the tip seam if the upper, as usual, is provided with a toe tip. The operator presents the shoe to the machine as accurately as he can in such manner that the toe gripper and the toe tacker are substantially central widthwise of the toe, the forepart of the last being between the side grippers and close to the inner jaws of these grippers. Because of the so-called swing of right and left lasts the heel end of a right shoe thus properly positioned is somewhat offset laterally toward one side of the machine and the heel end of a left shoe is correspondingly offset toward the other side of the machine, the extent of such offset with respect to a shoe of a given size depending upon the style of the shoe. To assist in controlling the shoe in the pulling-over operation there is provided a V-shaped heel rest which is moved lengthwise of the shoe into engagement with its heel end shortly after the starting of the cycle of operations of the machine after the grippers have gripped the upper and have begun to pull it. The heel rest initially occupies a substantially central position widthwise of the machine, but is so supported as to permit it to move laterally toward one side of the machine or the other side upon engagement Witheach shoe and therefore to adjust itself in accordance with the laterally offset positions of the heel ends of right and left shoes.

The present invention provides novel means for controlling the heel rest in such manner that instead of adjusting itself to each shoe as above described, it serves to determine the proper p0- sition of the heel end of each shoe laterally, whether it is a rightshoe' or a left shoe, and therefore insures the proper positioning of the forepart of each shoe in the above described relation to the grippers and the tackers without attention on the part of the operator. The construction shown comprises novel mechanism whereby the heel rest is swung automatically in directions widthwise of the machine to different initial positions adjustably determined in accordance with the style of the shoes operated upon and is thus properly positioned for use on right and left shoes of that style alternately. To render the heel rest thus properly effective in positioning each shoe prior to the starting of the machine, the construction shown is further such that the heel rest is engaged by the shoe when the operator presents the latter to the machine and is moved yieldingly from is initial predetermined position in a direction lengthwise of the shoe by pressure of the heel end of the shoe against it until the toe end of the shoe is properly positioned lengthwise relatively to the toe gripper, the direction of this movement of the heel rest being substantially parallel to the longitudinal median line of the heel end of the shoe, whether the shoe is a right shoe or a left shoe, The heel l rest therefore assumes, in accordance with the length of the shoe, a position which is that required for properly positioning laterally the heel end of a shoe of that style and size.

The novel features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In the drawings,

Fig. 1 is a view mainly in left-hand side elevation of a portion of the machine to which the invention is shown as applied, the parts being positioned as they are after a shoe has been presented but prior to the starting of the machine;

Fig. 2 is a view also mainly in left-hand side elevation, on an enlarged scale, of a portion of the structure shown in Fig. 1, illustrating by broken lines the Vpositions of certain parts at a particular time in the operation of the machine;

Fig. 3 is a view on an enlarged scale in the direction of the arrow III in Fig. 1, with some parts omitted, the position of a right shoe being provided with a toe gripper 2 for gripping theV margin of the upper and pulling the upper at the extreme end of the toe and with side grippers 6 for similarly operating on the upper at the opposite sides of the forepart. rIhe side grippers include pairs of jaws 8 which act on the upper in the Vicinity of the tip seam, when the shoe is provided with a tip, and include also pairs of jaws le which, in the use of the machine on adults shoes, act on the upper inlocations iarther from the end of the toe than the jaws 8. Associated respectively with the diierent grippers are mechanisms comprising wipers and tackers for wiping the margin of the upper inwardly over an insole on the last and for driving tacks to fasten vthe upper in pulled-over'position, the mechanism at the end of the toe Vbeing shown at I2 in Fig. l and one of the two mechanisms at the opposite sides of the forepart being shown at I4. At the end of the toe a single tackY is thus driven by a tack driver I, and by otherY drivers (not shown) at each side of the forepart a tack is driven substantially in the location of n the tip seam and one or more other tacks farthe end of the toe and other presser feet 22 whichV engage it in locations spaced apart widthwise of the shoe and farther from the end of the toe than the presser foot 20. In thus presenting the shoe the operator engages the toe-end face of theY last with one of the jaws 4, namely the innerV j aw, of the toe gripper, which thus determines the position of the shoe lengthwise in the machine, and positions the forepart of the last between the opposite side grippers the inner jaws of which are close to the sides of the last. If the shoe is properly presented the toe gripper and toe tacker will be centrally disposed widthwise of the toe so that the upper will be properly tensioned lengthwise and the tack will be driven substantially on the longitudinal median line of the forepart of the shoe. This requires that the Vheel end of a right shoe besomewhat offset lattively. -By means of pins 26 (Figs. 1 and 7) this heel rest is pivotally supported on two spaced arms 28 of a holder 3,0 for tipping vmovement about an axis extending widthwise of the shoe Vpulling-over machine.

to permit it to adjust itself in this respect to the shoe, such movement of the heel rest being limited by a screw 32 which is threaded therein and extends through a slot 34 formed in an extension 33 of one of the arms 28. The holder 3i! is secured by two screws 38 (Fig. 6) to a slide 4i) movable in directions lengthwise of the shoe, the holder having a tongue 42 (Fig. 7) which lits in a groove 44 in the slide. rest 'to be differently positioned relatively to the slide 4I! for better accommodation to shoes of different lengths, the slide 4t is provided with a plurality of such grooves 44 with corresponding holes to receivethe screws 38. The slide 4S is guided for movements in directions lengthwise of the shoe by a guideway in a carrier 46 supported as hereinafter described. Mounted in a bore in the slide is a tension spring 48 which is connected at one end to a pin 50 on'the slide and at its other end to a pin 52 on the carrier 46, the spring beingV partly housed within a casing 53 on the carrier. The spring, therefore, tends to move the slide 40 and the heel rest 24 in the direction to hold the heel rest against the shoe and positions the heel rest initially nearer the grippers 2 and 6 than when there is a shoe in the machine. Accordingly, in presenting a shoe the operator places its heel end against the heel rest and by pressure of the shoe on the heel rest moves the latter against the resistance of the-spring 48 until the toe end of the last is in proper position to engage'the inner jaw of theY toe gripper 2. When there is no shoe in the machine movement of the heel rest toward the grippers is limited by a pin 54 slidingly mounted in the heel rest holder 30 and extending into one or the other of two slots 53 (Fig. 4) formedV in the carrier 46. It'will be understood that in thus limiting movement of the heel rest the pin engages the carrier at one end Yof either slot. i

The two slots are provided to permit a preliminary adjustment of the heel rest forV comparatively large shoes or comparatively small shoes, so that in presenting a large shoe Vthe operator will not have to move the heel rest so farV against the resistance of the spring 43 as he would if there were no provision for such adjustment. Y In making the adjustment the operator withdraws the pin 54 from one of theslots 56 against the resistance of a leaf spring 58 which controls it, and after moving the heel rest to the proper position causes the pin to enter the other slot. It will be understood that the provision for securing the heel rest holder 30 in diiferent positions along the slide 4@ in the manner hereinbefore described permits a more precise initial adjustment ofthe heel rest for shoes of different sizes.

The carrier 46, which supports the heel rest as above described, is mounted for swinging movements in directions widthwise of theY shoe to carry the heel rest laterally to different initial positions for right and left shoesrespectively. For thisV purpose one end of the carrier is pivotally connected by studs 6E) to arms 62 of two bellcrank levers 64 pivotally mountedV on studs B5 which are supported in lugs 68 on 'a bracket lil.

YThis bracket has formed'thereon two ribs lI which'are secured to bars 72, these bars being held by binding screws 'I4 in fixed positions in grooves l5 formed in the head casting i8 of the The arrangement of the bell-crank levers 64 is such that as they are both swung, by means hereinafter described, in clockwise directions Vor in counterclockwise directions with reference 4to Fig. 3, they guide the heel rest To permit the heelV carrier 4B for swinging movements substantially about fan axis located at .r `(Fig. 3), the location of this iaxis being approximately at the junction of the `longitudinal median lines of the forepart and heel part of a shoe in the machine. The heel rest `24 is thus ycarried to the different positions required for right and left shoes. To assist further in guiding and controlling the carrier 46 in its swinging movements, two members 8D and 32 are secured respectively to the opposite ends of the-carrier, the member 80 overlapping and cooperating with an arcuate guide 84 fast on the bracket iii and the member 82 being similarly arranged in relation to an arcuate tongue Bt formed on the bracket. To limit the swinging movements of the carrier `I6 and thus to determine the proper initial positions of the heel rest for right and left shoes, there `are provided stops 8E arranged to be engaged respectively `by the opposite sides of the carrier, these stops being mounted for movements toward and from each other along guideways on the bracket '10. A shaft 9b rotatable in the bracket `by means of knobs S2 on its ends is provided with right and left screw threads in engagement with the stops for adjusting them equal distances toward or from each other as required for shoes of different styles.

For operating the bell-crank levers 64 to swing the .carrier it there is provided a bar 94, shown best in Fig. 7, which is guided for lengthwise `movements by the bracket 'It and by a member (25 on the bracket and an end portion of which is arranged to slide on the carrier. This end portion of the bar has thereon a iianged head it arranged to engage inwardly extending arms tit of the bell-crank levers 64. By reference to Figs. 3 and 4 it will `be `seen that when the heel rest carrier 45 is in the position there shown the arm 93 of one of the bell-crank levers is close to the head SS of the bar 94 While the corresponding arm of the other bell-crank lever is at a considerable distance from the head 96. Upon rearward movement of the bar, therefore, it serves -to swing the first-mentioned bell-crank lever in the direction to reverse the position of the heel Yrest `carrier 4G. Since the other bellcrank lever swings simultaneously in the same direction, 4its arm 98 in this operation `approaches the head S6. Accordingly the movement of the bar $4, effected as hereinafter described, is a short movement and serves only to initiate the swinging of the carrier 46. To complete the movement of the carrier there is provided what may be termed a reversing device |00. This device comprises two telescopic tubular members |02 and |94 pivotally connected respectively to the bracket l and the carrier 46 and having therein -an expansion spring |06 (Fig. 4). The device is so arranged relatively to the carrier that it is swung past a -dead-center position by the swinging movement of the carrier. This movement, as above stated, is initiated by the bar 94, the momentum of the carrier and of the parts thereon assisting in -the swinging of the device |053 past dead center. After the device passes dead center the spring IGS by its expansion completes independently the swinging movement of the carrier, the spring thereafter holding the carrier in the position determined by the appropriate stop 88. It will be under'- stood that as the carrier is thus swung the positions of the 'bell-crank'levers 64 are reversed, so that in response `to the next rearward movement of the bar 94 the carrier is returned to 6, its Vfirst position, .the bar acting on the arm 98 of the other bell-crank lever.

The `bar 94 is Vconnected at its rear end by `a link |03 to an arm |05 which isfast on a shaft |01 mounted to turn in the bracket lill and in one of the bars 12. Also fast on this shaft is an arm |08 connected by a link Il() to `an arm H2 mounted to swing about a pin H4 on the headcasting i3, the arm H2 having integral therewith an upwardly extending arm l i6. The upper end of thisA arm isin the path of a dog H8 pivotally mounted in the forked lower end of a member |26 which is `carried by a slide |22 movable horizontally in rearward and forward directions inthe head casting 18, the slide being operated by a rotatable path cam |24 engaging a roll |'2t thereon. The slide l|22 corresponds to the slide 10 shown in Letters Patent N o. 1,029,387 for moving the heel lrest of the machine therein shown forwardly into engagement with the heel enel of the `shoe in the first stage of 4the `cycle of operations of the machine. The slide 22, therefore, is moved in a rearward direction in the rst stage of the cycle, and as it moves in that direction the dog H8 is carried idly plast the arm l I since rit turns relatively to the member |26 upon Contact with the arm, as illustrated `by broken lines in Fig. 2. Near the end of the cycle, after the operations on the shoe have been completed, the slide is `moved reversely in a forward direction, and `at that `time the dog i i8 is `prevented from turning relatively "to the member itil by its engagement with a shoulder iZt on this member. Accordingly the arm `H55 is swung forwardly by the dog until the latter passes beyond it, thus imparting to the bar ed the amount of movement required to operate one or the 'other of the bell-crank levers 6s in the manner hereinbefore described. The position of the heel rest 24 is therefore reversed near the end of eachcycle, after the shoe has been released, so that it will be in positions for use on right and left shoes alternately. rihe dog |I8 passes beyond the arm |13 by the time the head 96 of the bar 94 is engaged by that arin SE which is vapproaching it as hereinbefore described, after which continued movement of that arm 98, as thereversal of the heel rest carrier 48 is 'completed by the device lot, serves to return the bar 94 to its initial position. Such return movement of the bar may be limited by its engagement with that portion of vthe bracket 'iii which is 'adjacent to the tongue 86.

"The manner of operation of the machine, in so far as it is of interest with reference to the present invention, will now be brieiiy summarized. The heel rest A24 is initially in a position widthwise of the machine appropriate for either a right shoe or a left shoe, and if it is not in position for the shoe which the operator rst takes up he may swing it to that position by hand, the spring iB 'being sufciently yieldable to permit this readily to be done. The stops 88 will be preliminarily adjusted as required by shoes of the style to `be operated upon and the slide 40 will be properly positioned initially for a range of sizes as determined by the pin 54 and one or the other of the slots 56. In presenting the shoe to the machine -the operator places its heel end against the heel rest and by the pressure of the shoe on the heel rest Vmoves the latter against the resistance of the spring 48 until the toe-end iface of the last is in position to engage the inner jaw 4 fof the toe gripper 2, the bottom of the forepart of the shoe then engaging the sole rest l8. At

Vaiusasis the Sametime theoperator positions the marginal portion of theupper materials properly between the jaws of the toe and side grippers. In thusY presenting the shoe the operator has no concern as to its position angularly, i. e., with respect to lateral swinging movement of its heel Vend, since this is determined by the heel rest.

Accordingly insurance is afforded that the toe gripper and toe tacker are centrally disposed widthwise of the toe and also that the foremost side tacks will be located in proper relation to the tip seam. The heel rest properlyfunctions in this respect in positioning shoes of different sizes, since the direction of its movement along its carrier 46 is substantially parallel to the longitudinal median line of the heel end of the shoe. That is, the heel rest assumes, in accordance with the length of the shoe, the -position required for properly positioning laterally the heel end of a shoe of that style and size, as predetermined by the position of the heel rest carrier 46 in engagement with one or the other of the adjustable stops It will be understood that in pulling-over machines of the type shown the toe gripper 2 and the presser foot 20 of the sole rest I8 are customarily adjusted in directions lengthwise of the shoe for shoes of different sizes so that the junction of the longitudinal median line of the forepart and that of the heel part of each shoe will be located approximately as indicated at m (Fig. 3) irrespective of size variations.

Having presented the shoe as above described, the operator starts the lpower operation of the machine, whereupon the grippers grip and pull the upper, the machine then coming to a stop to permit inspection of the upper and any necessary adjustment. In this rst stage of the cycle the slide |22' is moved in a rearward direction, the dog IIB passing idly over the arm I I6. After the machine has been started a second time, the side clamps l1 are moved inwardly to clamp and hold the shoe at the sides of the forepart and the wiping and tacking mechanisms I2 and i4 are then operated to wipe the margin of the upper inwardly over the insole and to drive the upperfastening tacks, the grippers releasing-the upper. Thereafter the parts which operate on the shoe are returned to starting positions and the shoe is released by the side clamps, the operator holding it in his hand to prevent it from falling. Near the end of the cycle the slide 22 is moved forwardly and causes the dog H8 to swing the arm IIB in that direction. This serves to move the bar 94 in a rearward direction, causing the head S6 on the bar to engage that arm 98 which is adjacent thereto and to start the swinging movement of the bell-crank lever 64 of which that arm is a part, thus initiating the reversal of the heel the movement of the heel rest carrier the bar 94 is returned by the action of the arm 98 of one of the bell-crank levers 64 thereon in the manner hereinbefore explained.

In a shoe machine, the combination with means for operating on the foreparts of shoes, of a heel rest for engaging the heel end of each shoe to control the shoe, a member movable to carry the heel rest along a pathextending lengthwise of each shoe in response to pressure of the heel end of the shoe onthe heel rest when the operator presents Ythe Vshoe to the machine, a spring for yieldingly opposing the movement of the heel rest along said path, another lmember relatively to which said rst-named member and the heel rest are thus movable, one of said members having slots therein in diierent locations lengthwise of the path of movement o f the heel rest, and a pin on the other member arranged to be inserted in said different slots selectively to position the heel rest initially in different locations along its path of movement for shoes of different lengths while permitting it to be moved from each of said locations against the resistance of the spring by the pressure of the shoe thereon.

21. In a shoe machine, the combination with means foroperating on the foreparts of shoes, of a heel rest for engaging the heel end of each shoe to control the shoe, a slide to which the heel rest is secured, a support having a guideway for said slide to permit the heel rest to be moved along a path extending lengthwise of each shoe in response to pressure of the heel end of the shoe thereon when the operator presents the shoe to the machine, a spring for yieldingly opposing such movement of the heel rest, said support having slots therein in different locations along the path of movement of the heel rest, and a pin movable with the heel rest and arranged to be inserted in said different slots selectively to position the heel rest initially in diierent locations along its path ofrmovementV for shoes of different lengths while permitting itto be moved from each of said locations against the resistance of the spring by the pressure of the shoe thereon.

22. In a shoe machine, the combination with means for operating on the foreparts of right and left shoes, of a heel rest for engaging the heel end of each shoe to control the shoe, said heel rest being mounted for lateral movements to diierent positions for right and left shoes respectively, means for initiating movement of the heel rest from either of said positions toward the other position, and additional means for completing independently the movement of the heel rest thus initiated.y

23. In a shoe machine, the combination with means for operating on the foreparts of right and left shoes, of a'heel rest for engaging the heel end of each shoe to control the shoe, said heel rest being mounted for lateral movements to different positions for right and left shoes respectively, means for initiating movement of the heel rest from either of said positions toward the other position, and spring means mounted for movement past a dead center position -for thereafter completing independently the movement or" the heel rest thus initiated.

24. In a shoe machine, the combination with means for operating on the foreparts of right and left shoes, of a heel rest for engaging the 13 heel end of each shoe to control the shoe, a heel rest carrier mounted for movements in opposite directions to carry the heel rest laterally to di ferent positions for right and left shoes respectively, means for initiating movement of said carrier to carry the heel rest from either of said positions toward the other position, and a device `niounted for swingingr movement past a dead center position by the movement of the carrier thus initiated, said device comprising two telescopic members and a compression spring therein for completing the movement of the carrier after the device has passed its dead center position.

25. In a shoe machine, the combination with means for operating on the foreparts of right and left shoes, of a heel rest for engaging the heel end of each shoe to control the shoe, a heel rest carrier supporting said heel rest, bell-crank levers mounted for swinging movements about 2 diierent axes extending heightwise of the shoe and pivotally connected to said heel rest carrier respectively in different locations to guide the carrier for swinging movements in opposite directions to carry the heel rest laterally to dilerent positions for right and left shoes respectively, means for initiating movement of said carrier in one direction by force applied to one of said bell-crank levers and in the opposite direction by force applied to the other bell-crank lever, and spring means mounted for movement past a dead center position by each movement of the carrier thus initiated for thereafter com-` ple-ting that movement of the carrier.
